Kirupa's XML Gallery (Additional Dynamic Text)

Hi all, hope you can help me out…

I stumbled on Kirupa’s tutorial on his XML guide and I think it is excellent! I plan to use multiple versions of it to setup a tier-level gallery, but I am coming into an issue…

I have tried to add a new description text field to call data from a new child node I’ve created called description. Everything else loads when adding the new code, but the text field remains “undefined”:

[COLOR=#003366]function loadXML(loaded) {[/COLOR]
[COLOR=#003366]if (loaded) {[/COLOR]
[COLOR=#003366]xmlNode = this.firstChild;
image = [];
description = [];
caption = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++ ) {[/COLOR]
[COLOR=#003366]image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
caption* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;[/COLOR]
[COLOR=#003366]}
firstImage();[/COLOR]
[COLOR=#003366]} else {[/COLOR]
[COLOR=#003366]content = “file not loaded!”;[/COLOR]
[COLOR=#003366]}[/COLOR]
[COLOR=#003366]}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load(“images.xml”);

everything looks to be in order. if you want to troubleshoot though, you might try:

  1. make sure the XML tag is different from the others (and closed).
  2. change the name desc_det to something not so similar to the other one.

changing desc_det to capt_txt worked, thx :krazy:
